Great battery life. One of my friend using this mobile.
Better camera than redmi note 3. Looks great in hand.
Everything is great except the unavailability of fast charging, which is a great disappointment for me not to buy this. Snapdragon 625 takes great for processing the power in everyday use. Heavy gaming like aspalt 8 slightly seen the frame drops but at its price range its OK. 4 GB ram is enough for every multi tasking but ram management is bad, most third party application reloaded after some minutes. Company needs to work on their own MIUI to smoothing the performance.
My suggestion to Xiaomi to add fast charging from its successor series, bcoz competition is going to tough for you.
